Never dealt with this type of issue before. Putting a short guide here for anyone else who Ctrl+F’s their way here or from google.

**Issue:**  
UE5.6.1 seems to have an old version of “Magick” which is one of many dependencies used in the engine source code. Specifically here, for some automation stuff. It has a known vulnerability and therefore when trying to package and compile, users may get stops and errors.

**Solution:**  
Update the source code to use the latest stable version without vulnerabilities.

- Open UE5 solution, click the `Manage NuGeT Packages` in the orange banner
- Select the checkbox `show vulnerable only` on the left, select Magick
- Scroll on the right and select the boxes only by the lines where it has the old version
  - Select all 3 boxes

- Below the box selection, change the dropdown from 14.7.0 to Latest Stable (14.8.2) in the `Version`
  - Click the `Install` Button to the right

- Click ok in the following prompts, close with saving
- Re-open the sln file. Do a full build and confirm no errors

Wow yeah that did it. I don’t know what I would do without you guys on the forum. I never would have found this. Magick was on the wrong version. So dumb.

Thanks!
